Description

[Technical field]

[0001] The present invention relates to a windscreen wiper blade adapter, to a wiper blade equipped with such an adapter, to a wiping system comprising such a wiper blade, and to a method of assembling such a wiping system.

[0002] The present invention relates to the field of wiping and / or cleaning glazed surfaces of motor vehicles. [Background technology]

[0003] Generally, a wiping system for a motor vehicle comprises at least one wiper arm intended to perform a reciprocating angular movement, to which a wiper blade with a wiper rubber is connected, which comes into contact with the glass surface of the vehicle and is driven by the reciprocating angular movement of the wiper arm, to wipe and / or clean the glass surface in order to ensure a clear and unobstructed view for the driver of the vehicle in case of bad weather or when washing said glass surface. To ensure the connection between the wiper blade and the wiper arm, the wiping system is equipped with an adapter, which interacts with the wiper blade on the one hand and with the end of the wiper arm on the other hand.

[0004] This connection makes it possible to replace the wiper blade when it becomes worn. It is well known practice to provide such a connection by means of a magnetic connector, which has the advantage of improving the ergonomics of assembling the wiper blade onto the wiper arm.

[0005] However, disassembly is not the best since it requires either pressing a push button to release the connection or removing the magnet with a vertical translational movement, and removing the magnet is also not very ergonomic since it can require a lot of effort to remove the magnet. Summary of the Invention [Problem to be solved by the invention]

[0006] The present invention improves the ergonomics of this magnetic connection system. [Means for solving the problem]

[0007] The present invention comprises an adapter for a vehicle wiper blade comprising a mechanical connection region configured to receive a tab of the wiper arm and a magnetic connection region configured to receive at least one permanent magnet and interact with the wiper arm.

[0008] The adapter according to the invention comprises a body and a head, a mechanical connection area is provided for inserting one end of a wiper arm, the mechanical connection area comprising a hole into which the end of the arm is inserted and an inner wall of the head against which the end of the arm bears and pivots.

[0009] The adapter is fixed firmly to the wiper arm by a magnetic connection at the magnetic connection area of ​​the adapter by bringing the wiper blade onto the wiper arm.

[0010] Advantageously, disassembly of the wiper blade is ergonomic since it is achieved by tilting about the mechanical connection area, and tilting does not require significant effort to remove the permanent magnet from the wiper arm.

[0011] According to one aspect of the invention, the magnetic coupling region comprises a receiving region configured to receive a permanent magnet.

[0012] According to this embodiment, the receiving area is a cavity in which the permanent magnet is accommodated so as to embed it in the thickness of the top wall of the adapter. This prevents the magnet from protruding from this wall and causing mechanical interference. The receiving area may also be a rectangular area longitudinally and transversely bounded by separate studs and intended to accommodate the permanent magnet. The function of these different types of receiving areas will be explained in more detail below.

[0013] According to one aspect of the invention, the adapter includes at least a permanent magnet that is rigidly fixed, press-fit, adhesively bonded, or overmolded to the adapter by form interaction within the receiving area.

[0014] The permanent magnet is ideally a neodymium magnet in order to provide a strong magnetic field. The permanent magnet must be rigidly fixed to the adapter in a manner strong enough to withstand the mechanical forces exerted when the wiping system is in operation. Thus, all the various fixing means described above are shown to meet this condition.

[0015] Of course, other compositions of permanent magnets are contemplated depending on the particular needs of each embodiment of the invention.

[0016] According to one aspect of the invention, the adapter includes at least one detent that holds the permanent magnet in place.

[0017] The adapter includes at least one claw disposed about the permanent magnet receiving area. The shape of the claw in this case serves to define a free space corresponding to the thickness of the permanent magnet. The tip of the claw is curved toward the upper surface of the permanent magnet to keep the permanent magnet within its receiving area. Thus, the permanent magnet is not subjected to motion when the wiping system is operating.

[0018] According to one aspect of the invention, the adapter includes at least one flexible tongue that retracts for insertion of a permanent magnet under the prongs and holds the permanent magnet in a fixed longitudinal position.

[0019] During assembly, the permanent magnet is slid by longitudinal translation under the pawl. The pawl prevents lateral movement of the magnet, and stop means in the permanent magnet receiving area prevent longitudinal movement of the permanent magnet in the translational direction during assembly. To prevent longitudinal movement in the opposite direction, the adapter includes a flexible tongue at its longitudinal end, which bends towards the wiper blade as the permanent magnet is translated and inserted under the pawl. Once the permanent magnet is inserted, the flexible tongue returns to its initial position, thus preventing longitudinal movement in the opposite direction to the insertion direction of the permanent magnet.

[0020] The magnetic coupling area equipped with a permanent magnet is configured to interact with the wiper arm.

[0021] In another embodiment, the magnetic connection area equipped with a permanent magnet is configured to interact with a rod of a wiper arm, such rod being equipped at its end with a yoke.

[0022] In another embodiment, the magnetic connection area equipped with a permanent magnet is configured to interact with a yoke of the wiper arm, such yoke being rigidly fixed to a rod constituting the wiper arm.

[0023] The rod is crimped into a U-shaped yoke extending in the transverse section to ensure mechanical retention of the rod. The rod and / or the yoke are made of metal to ensure a magnetic connection with the permanent magnet of the adapter.

[0024] According to one aspect of the invention, the adapter includes a head and a body, the head being wider and taller than the body, and a hole configured to receive a tab of a yoke of a wiper arm.

[0025] The difference in dimensions between the head and body of the adapter creates an additional stop means when the arm / blade connection is made. The yoke presses against a shoulder created by this difference in height between the two elements of the adapter. The holes then allow for the insertion of tabs emerging from the ends of the yoke, thus creating a mechanical retention means when the arm and blade are connected. The holes are located across the head and body to allow the yoke to be placed in position while ensuring that it abuts against the shoulder provided at the interface between the head and body.

[0026] The adapter extends longitudinally and includes at least one wall forming a stop means configured to interact with the wiper arm to longitudinally lock the adapter relative to the arm.

[0027] When the connection between the wiper arm and the wiper blade is made, the stop means maintains the longitudinal connection such that the connection between the wiper blade and the wiper arm withstands the centrifugal forces caused by the reciprocating angular movement of the wiper arm when the system is operating.

[0028] The walls forming the stop means are supported by L-shaped extensions provided at the longitudinal ends of the adapter, extending in a longitudinal plane.

[0029] In this embodiment, the stop means interacts with the rod and / or yoke of the wiper arm, resulting in optimal retention of the wiper blade.

[0030] The adapter has a U-shaped cross section extending in transverse plane defined by a top wall and two side walls, the wall forming the stop means being supported by a projection emerging from at least one of the side walls.

[0031] In this embodiment, the stop means is arranged on the side wall of the adapter. The stop means extends perpendicularly on the side wall and forms a protrusion on the adapter. The yoke in this embodiment comprises a notch intended to receive the stop means of the adapter. This stop means prevents the longitudinal movement of the wiper blade.

[0032] According to one aspect of the invention, the adapter includes a magnetic shield configured to be interposed between a body of the adapter and a permanent magnet.

[0033] It is possible to include a magnetic shield under the permanent magnet, which is a metal part with dimensions equal to or greater than those of the magnet, for pushing the magnetic field of the magnet towards the wiper arm in order to strengthen the magnetic connection resulting from the magnetic connection area, the magnetic force is then concentrated towards the yoke of the wiper arm, improving the magnetic connection between the wiper arm and the wiper blade with an increased output of magnetic force.

[0034] According to one aspect of the invention, the magnetic shield includes at least one loop that interacts with at least one tab of the adapter to securely secure the magnetic shield to the adapter.

[0035] The magnetic shield includes at least one loop on a side wall of the magnetic shield. The size of this loop is such that the pawl that holds the permanent magnet can be inserted into the loop. The magnetic shield is thus attached by the interaction between the loop and the pawl. The presence of the magnetic shield never encroaches on the space left by the pawl for the translational insertion of the permanent magnet.

[0036] The present invention also encompasses a wiper blade of a vehicle wiping system comprising at least one adapter as described above.

[0037] The adapter is connected by a pivot link directly to a connector that supports the wiper blade, so that a wiper blade having such an adapter can be mounted on any type of vehicle having a wiper arm that is complementary to the wiper blade and allows for mechanical and magnetic connection.

[0038] The present invention also includes a vehicle wiping system comprising a wiper arm and a wiper blade as described above.

[0039] The wiper arm includes a rod crimped into the yoke, the rod forming a connection between the yoke and an end of the arm, the end of the arm being directly connected to a device for actuating the reciprocating motion of the wiping system. The wiper blade is as described above and includes an adapter as described above.

[0040] The invention also relates to a method for assembling a wiper blade on a wiper arm, the method comprising the steps of: inserting a tab emerging from a longitudinal end of a yoke of the wiper arm into a hole in the adapter; Pivoting the blade relative to the arm about a pivot axis passing through an area of ​​mechanical connection between the tab and the adapter; creating a magnetic connection between a permanent magnet rigidly fixed to the wiper blade adapter and the wiper arm; Includes.

[0041] The tabs of the yoke are inserted into the holes of the adapter. Thanks to the pivoting movement of the blade, the tabs ensure the mechanical retention by coming into direct contact with the inner wall of the adapter. This contact area corresponds to the mechanical connection area. The pivoting of the blade also brings the permanent magnet up to the metal part of the wiper arm that is intended to interact with the permanent magnet. This is done until a magnetic connection area is created. [Brief description of the drawings]

[Figure 9b] 13A-13C show another alternative design of an adapter having adaptable elements for any embodiment. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0043] FIG. 1 shows a general view of a wiping system 25 of a motor vehicle. The wiping system 25 comprises a wiper blade 2 and a wiper arm 5. The wiper blade 2 includes an adapter 1, a connector 34 and a wiper rubber 24. The wiper rubber 24 is in direct contact with the glass surface of the vehicle and cleans said surface. The connector 34 forms the connection between the wiper rubber 24 and the adapter 1. The adapter 1 is mostly hidden by the yoke 14 of the wiper arm 5 and will be described in more detail below. The adapter 1 is directly connected to the yoke 14 and thus ensures the connection between the wiper blade 2 and the wiper arm 5.

[0044] The movement of the wiper blade 2 is caused by the wiper arm 5. The wiper arm 5 comprises a drive 35, a yoke 14 and a rod 27 crimped in the yoke 14. The yoke 14 is an element that connects to the adapter 1 via mechanical and magnetic connection areas. The yoke 14 is crimped onto the rod 27, this crimping providing the connection between the yoke 14 and the rest of the wiper arm 5. The drive 35 has one end connected to a motor for rotating the wiping system 25.

[0045] The adapter 1 is shown in more detail in FIG. 2 with a first embodiment. The adapter 1 consists of a head 11 and a body 12. The head 11 is arranged at the longitudinal end of the adapter 1. The head is wider and higher than the body 12, thus creating a shoulder 16, the walls of which correspond to the difference in width and height between the head 11 and the body 12. A hole 13 arranged across the head 11 and the body 12 is intended to receive one end of the yoke and thus create a mechanical contact between the yoke and the adapter 1 in the mechanical connection area.

[0046] The body 12 consists of a U-shaped portion 18 having a top wall 19 and two side walls 20 arranged on either side of the top wall 19. The body 12 also comprises, on its outer surface, a receiving area 8 intended to receive a permanent magnet 7, shown in an exploded view. The permanent magnet 7 is rigidly fixed in the receiving area 8 by form interaction, press-fit, adhesive bonding or overmolding. In this embodiment, the receiving area 8 is a cavity such that the permanent magnet 7 is embedded in the thickness of the surface of the body 12 of the adapter 1 such that the upper surface of the permanent magnet 7 is substantially aligned with the upper surface of the body 12 of the adapter 1.

[0047] Opposite the head 11, the end of the body 12 includes an L-shaped extension 17 extending in a longitudinal plane. This L-shaped extension 17 has a recess 37 which creates a stop means 15 intended to prevent the longitudinal movement caused by the operation of the wiping system 25 by maintaining the connection between the adapter 1 and the yoke 14. The L-shaped extension 17 ends in two projections 36 which extend upwards to interact with the wiper arm to improve the connection of the wiper blade to the arm.

[0048] FIG. 3 shows an adapter 1 identical to that of FIG. 2. The view from below shows the inner wall 28 of the adapter 1. The inner wall 28 is formed by a series of disks formed on the inner surface of the head 11 of the adapter 1. The inner wall 28 is juxtaposed with the hole 13. At the inner wall 28, the contact between the wiper blade and the wiper arm takes place by the inner wall 28 and the yoke of the adapter 1, respectively. A fastening means 26 is present below the body 12 and extends laterally between the two side walls 20. This fastening means 26 ensures the connection between the adapter 1 and the connector 34 according to FIG. 1.

[0049] The adapter is designed to interact with a yoke 14 of a wiper arm, which yoke 14 is shown from below in figure 4. The yoke 14 has an elongated U-shape in cross section and is configured to be crimped onto a rod 27.

[0050] A tab 4 is present at the free end of the yoke 14. This tab 4 has a slightly curved shape that is complementary to a series of disks formed on the inner surface of the head of the adapter. This tab 4 is responsible for the mechanical contact between the adapter and the yoke 14 in the mechanical connection area. The tab 4 is intended to be inserted into a hole in the adapter and to establish a direct contact with the inner wall in the mechanical connection area.

[0051] The rod 27 is made of metal and allows the connection with the rest of the wiper arm. In this embodiment, the rod 27 also has the function of magnetically interacting with an adapter in the non-crimped part of the yoke 14. The shape of the rod 27 varies depending on the type of adapter it interacts with.

[0052] One end of the rod 27 is flat. One end of the rod corresponds to an interaction part 33 that interacts with the permanent magnet. The magnetic connection area is therefore the contact area between the permanent magnet of the adapter and the interaction part 33 of the rod 27.

[0053] The rod 27 has a thickness difference between the interaction portion 33 and the remaining portion of the rod 27, creating the rod stop means 32. When the connection between the wiper blade and the wiper arm is made, the rod stop means 32 comes into direct contact with the stop means 15 of the adapter, since the stop means 32 is housed in a recess of the adapter formed between the L-shaped extension and the receiving area. This contact increases the resistance to the centrifugal forces caused by the operation of the wiping system. The contact between the adapter stop means and the rod stop means 32 helps to maintain the connection between the wiper blade and the wiper arm.

[0054] The rod 27 comprises two recesses 31 arranged between the rod stop means 32 and the crimping area of ​​the yoke 14. The recesses 31 are arranged such that when the connection between the wiper blade and the wiper arm is established, they face the L-shaped extension, more specifically they lie on a protrusion on the L-shaped extension.

[0055] FIG. 5 is a longitudinal cross-sectional view of the connection between the wiper blade and the wiper arm. The cross-section is taken along a cross-sectional plane formed by the longitudinal and vertical axes. The yoke 14 is also shown in full view to explain how the connection between the wiper blade and the wiper arm is made. Several steps are required to establish the connection between the wiper blade and the wiper arm, namely: - the tabs 4 of the yoke 14 are inserted into the holes 13 of the adapter 1, The pivoting movement of the wiper blade is carried out about a pivot axis 39 passing through the mechanical connection area 3 between the tab 4 and the adapter 1 in order to establish, on the one hand, mechanical contact between the tab 4 of the yoke 14 and the inner wall 28 of the adapter 1 in the mechanical connection area 3, and, on the other hand, magnetic contact between the permanent magnet 7 of the adapter 1 and the interaction part 33 of the metal rod 27 in the magnetic connection area 6.

[0056] Figure 5 focuses on two connection areas between the wiper blade and the wiper arm. The mechanical connection area 3 is located on the left side of the figure. This is the contact point between the tab 4 of the yoke 14 and the inner wall 28 of the adapter 1. After inserting the tab 4 into the hole 13, the pivoting movement of the wiper blade 2 causes direct contact between the surface of the tab 4 and the surface of the inner wall 28 in the mechanical connection area 3.

[0057] The magnetic connection area 6 is arranged at the contact point between the permanent magnet 7 and the interaction part 33 of the rod 27 and is indicated by a dotted line.

[0058] When the assembly process is completed, the connection between the wiper blade and the wiper arm is finished. The yoke 14 is held in a fixed longitudinal position by the contact between the end of the yoke 14 and the shoulder 16 of the head 11 of the adapter 1. The same function is provided between the rod stop means 32 and the stop means 15 of the adapter 1. These two contact points are not shown in FIG. 5. This longitudinal retention is strengthened by the interaction between the protrusions on the L-shaped extension 17 of the adapter 1 and the recesses 31 of the rod 27. The recesses 31 of the rod 27 are two empty spaces formed in the rod 27. When the connection between the wiper blade and the wiper arm is established, the protrusions on the L-shaped extension 17 of the adapter 1 fill the empty spaces created by the recesses 31 of the rod 27, thereby strengthening the maintenance of the longitudinal connection.

[0059] A second embodiment of the adapter 1 for the wiper blade 2 and the yoke 14 for the wiper arm is also possible.

[0060] A second embodiment of the adapter 1 is shown in Figure 6. This adapter comprises a head 11 and a body 12 of different widths and heights so as to create a shoulder 16. The body 12 again consists of a U-shaped portion 18 extending in cross section, with a top wall 19 and two side walls 20.

[0061] The difference between the two embodiments lies in the area for receiving the permanent magnet 7 and in the longitudinal holding mode between the wiper blade and the wiper arm. The area for receiving the permanent magnet 7 is a rectangular area bounded longitudinally and laterally by studs 29. In this embodiment, the permanent magnet 7 is adhesively bonded to the receiving area. The studs 29 are separate from one another and bound the periphery of the permanent magnet 7. The permanent magnet 7 is positioned in the receiving area such that the upper surface of the permanent magnet 7 is substantially aligned with the upper surface of the body 12 of the adapter 1.

[0062] The shoulder 16 is the only stop means common to both embodiments. In this embodiment, the stop means for enhancing the longitudinal retention is located on the side wall(s) 20 and takes the form of at least one lateral projection 21 on the side wall 20. The lateral projection 21 has a laterally extending parallelepiped shape and interacts with the yoke, as will be described below.

[0063] A second embodiment of the yoke 14 is shown in Figure 7. As in the first embodiment, the yoke is provided at its free longitudinal end with a tab 4. The function of the tab 4 is exactly the same as that described in the first embodiment.

[0064] Magnetic contact is established directly with the yoke 14 via contact portions 38 disposed on the inner wall of the yoke 14 and shown in dotted lines.

[0065] The structure of the yoke 14 differs in this embodiment due to the presence of at least one notch 30 on at least one of the side walls of the yoke 14. The notch 30 is arranged laterally at the height of the contact portion 38. The notch 30 is V-shaped extending in a plane parallel to the longitudinal direction and has the function of interacting by direct contact with a lateral protrusion arranged on the side wall of the adapter as will be described below.

[0066] Figure 8 shows the connection between the yoke 14 and the adapter 1 of the second embodiment. The assembly method is the same as in the first embodiment. The magnetic connection area is characterized by the contact point between the permanent magnet 7 and the contact part 38 of the yoke 14 and is shown by the dotted line.

[0067] The difference between the embodiments seen in figure 8 concerns the longitudinal retention of the connection. Once assembled, the longitudinal retention is ensured by the contact point between the lateral projection 21 of the adapter and the notch 30 of the yoke 14. The lateral projection 21 is thus received in a V-shape in the form of the notch 30. Although the structure of the stop means differs in the two embodiments, the function remains the same, i.e. to retain the wiper blade longitudinally against the centrifugal forces caused by the reciprocating angular movement of the wiper arm.

[0068] It will be clear that in other possible embodiments it may be the case that the lateral projections 21 have simple vertical edges without any notches.

[0069] Figures 9a and 9b show alternative means of mounting in the area for receiving the permanent magnet 7. These variants can be applied to any of the embodiments presented above.

[0070] In Figures 9a and 9b, the area for receiving the permanent magnet 7 comprises a magnetic shield 22 arranged between the body 12 of the adapter 1 and the permanent magnet 7, which in this case has been truncated for visibility. The magnetic shield 22 is a bent metal plate, which redirects the magnetic flux lines towards the magnetic connection area, which would normally be directed towards the adapter 1 in the absence of such a magnetic shield. This increases the magnetic strength of the permanent magnet 7 and improves the magnetic connection between the permanent magnet and the yoke or rod when the connection between the wiper blade and the wiper arm is made.

[0071] Unlike the above embodiments in which the permanent magnet 7 is adhesively bonded or overmolded, in Figures 9a and 9b the permanent magnet 7 is held in place by shape interactions. Nevertheless, the permanent magnet 7 is always positioned such that the top surface of the permanent magnet 7 is substantially aligned with the top surface of the body 12 of the adapter 1.

[0072] To fix the position of the magnetic shield 22, the magnetic shield is equipped with at least one loop 23, advantageously two loops 23 per side. The loops 23 are arranged on both sides of the magnetic shield 22 and are curved downwards. In FIG. 9a, the loop 23 interacts with a protrusion 41 extending laterally to the adapter 1. The protrusion 41 is thus of such a size that it can pass through the loop 23. This arrangement allows a firm fixation of the magnetic shield 22 to the adapter 1.

[0073] The permanent magnet 7 is held in place by ridges 42 arranged on the longitudinal ends and lateral walls of the area for receiving the permanent magnet 7. In FIG. 9b, the adapter 1 comprises at least one claw 9, advantageously several claws 9, formed in the receiving area 8 for accommodating the permanent magnet 7 and made directly integral with the adapter 1. The claws 9 define a free space corresponding to the thickness of the permanent magnet 7. The tips of the claws 9 are chamfered towards the upper surface of the permanent magnet 7 so as to hold the permanent magnet in its receiving area, thus avoiding operations for mounting the permanent magnet 7, such as adhesive bonding or overmolding. To interact with the chamfered portion of the claw 9, the permanent magnet 7 is provided in this case with a chamfered surface 40 in the part that interacts with the claw 9. The permanent magnet 7 is thus inserted by a longitudinal translation 43 between the magnetic shield 22 and the chamfered portion of the claw 9.

[0074] However, in other embodiments not shown, the permanent magnets 7 can be held in place by overmolding the adapter 1 on the body, in combination with or instead of mechanical retention means as in the embodiments described above. This type of configuration would be particularly advantageous for protecting magnets made of compositions prone to corrosion (e.g. some neodymium magnets) without the need to apply a protective coating to the magnets.

[0075] 9a, in FIG. 9b, the magnetic shield 22 is equipped with at least one loop 23, advantageously two loops 23 for three claws 9, the claws 9 being alternately inserted or not inserted into the loops 23. The loops 23 are arranged on both sides of the magnetic shield 22 and are curved downwards to interact with the claws 9. The claws 9 are thus sized to allow them to pass through the loops 23. This arrangement allows the magnetic shield 22 to be rigidly fixed to the adapter 1.

[0076] In Figure 9b, the adapter 1 is provided with a flexible tongue 10 at its rear longitudinal end, i.e. opposite the end where the head is formed, which retracts during the insertion of the permanent magnet 7 under the claw 9 in longitudinal translation 43. Once the permanent magnet 7 has been inserted, the flexible tongue 10 performs a return movement back to its initial position, thus preventing longitudinal movement of the permanent magnet 7 in the direction opposite to the insertion direction.
